The 'present `invention relatesto ai sewingfmar chine; having` a.vertical. mountingiplate shaped approximately like. the. machinel. and'Vset. at:` a right` angle, withthe.; normal direction: of; the seam, thefunction of said platelbeinggtorsupport the.- various; mechanical'.parts a in: working order, without the helpt` of` an outer-shell:or--housng-A Referring;V more." particularly to; the drawings wherein'vI2 have.` represented` two embodiments of my invention., Fig, 1 is a:view off. themachine with its outer shellpa-rtly tornol showing; thefirst embodment; Fig..V 2 shows a cross-section along-.H-IL of\Fig..1;Eig, 3 isa, crossfsection on. a'slarger, scaleg, FigA is.a.view. frombeneath. of ar machine accordingto fthe second:` embodiment; the basebeing removed;1ig= 5:isa cross-section alongV-V ofFig'rfi` The machineaccording to the first embodiment asshown in..Fig-s.=.lto: 3comprisesffanbaso'supporting a generally G-shapedl-mounting plate 3 bymeans of screws 2. This plate 3 is located in a plane set at rightangles to the path, travelled by the seam; said-*pathbeingitselfperpendicular tothe planeof the drawing. The-material is guidedunder the needle.: by the presserfoot 4. The contour of` plate 3corresponds. approximately with the contour4 of. the. machine. thisbeing true throughout' its lower arm 3a, its upper arm 3b, its head 3c,and its vertical shank 3d.

The plate 3 bears all the mechanical parts with the exception of theelectric motor, encased in a lateral bulge of the outer shell (see Fig.2).

The bearings of the shafts of the wheel 6 driven by the motor, and ofwheels 'I and 8 driven in turn by a belt 9, and of wheel 8 are all partof plate 3.

The crosses II) mark the places of the other bearings of the loop takingdevice, of the driving levers, of the feed-dogs, and of the rodcontrolling the lateral displacement of the needle I I as well as of theslack thread controlling lever I2 etc. It is to be understood that allpossible constructions are not shown here, the character of theinvention being that the machine shall be able to run with its outercase removed, all parts being supported by the mounting plate.

This makes for great simplicity in the assembling of the machine and inthe timing and checking of its elements, which can all be easily reachedfor cleaning or repairing purposes.

The machinery is protected by a thin case formed by two shells I3 andI4.

These two shells are also supported by the plate 3 by means ofcross-members I5, IB (see Fig. 3), and a screw I1 and a nut I8.

Another-departure?fromvthe conventional sewingfmachine lies inthefactthat the fly-wheel 8 is ina'planeyparallel to the plane-ofthe-drawing; (plane-of the mounting plate) `instead of beingperpendicular to it. Thisafords the use of an endless. belt 9 furthedrive ofthe Wheels 6 and 'I lyingjnqthe same planeinstead of gears.

The-shells., or at least onecf` them, have anapertureenablingthefoperator to hold the rim of the. fly-wheel 8, for,the purpose of` starting or stopping. the machine. v

The bulge 5, protecting the motor could be part of the shell I4, and theshells I3 and I4 could be divided in several parts, for instance at thelocation of the head, in order to give access to the parts holding theneedle or the slack thread controlling lever, or at the extremity of thelower arm in order to give access to the loop taking device and thebobbin case.

In the second embodiment the mounting plate 2i) is not fixed to the basebut instead it is supported by the two outer shells 24 and 25 as can beseen on Figs. 4 and 5. In this embodiment the plate 20 and the motor 2|are rigidly connected by cross-members 22 forming an assembly that willremain upright without the help of the plate or the base.

As in the first embodiment, the plate 20 is connected to the shells 24and 25 by means of crossmembers, here designated 23. But, contrary tothe first embodiment, the connection to the base is not provided by theplate, but by the shells, which are provided with embossments 26, 21 and28, and screws 29 (see Fig. 5).

The drawings show only some of the parts of the machinery, such as thepulley 30 which takes the place of the wheel 6 of Fig. 1, but it is tobe aetdsot understood that the plate 20 supports all operative parts ofthe machinery in working order, including the motor.

To take the machine apart, it will be sufficient to'unscrew the base andto remove the shells. A block of machinery will remain, made up of themounting plate 2i), the operating mechanism supported thereby, andthemotor, the whole being in working order so as to afford an easyinspection of the operation of all parts and to permit convenientcleaning, repairs, and replacement of parts if necessary.

W hat I claim is:

l. In a sewingmachine, the combination of a base; a supporting standardoi substantially C- shaped, plate formation rising from said base; asewing needle and presser foot assembly operatively mounted across theopen mouth of said supporting standard; drive mechanism mounted on saidsupporting standard, and comprising a series of drive wheels operativeiyinterconnected by aV drive beit, the wheels of said series being mountedfor rotation on respective axes which are perpendicular to the plane orsaid supporting standard; and a substantially Similarly' C-shapedhousingrenclosing said supporting standard and the said drive mechanismmounted thereon.

2. 1n a sewing-machine, the combination of a base; a supporting standardof substantially C-shaped, plate formation secured to'and rising fromsaid base; a sewing needle and presser' foot assembly operativelymounted across the open mouth or" said supporting standard; drivemechanism mounted on said supporting standard, and comprising a seriesof drive wheels operatively interconnected by a drive belt, the wheelsof said series being mounted for rotation on respective axes which areperpendicular to the plane of said supporting standard, one of thewheels of said series being a riy wheel mounted so as to projectrearwardly oi said supporting standard; and a substantially similarlyCV-shaped housing enclosing said supporting standard and the said drivemechanism mounted thereon, said housing having an aperture in its rearwall, through Vwhich, a segment of the rim yof said fly Wheel projectsto be available for manual manipulation.

3. The combination recited in claim 1, wherein the sewing needle andpresser foot assembly are mounted in a plane transverse to the plane ofthe supporting standard, so as to sew a seam substahtiallyperpendioularly to the plane of said supporting standard.

Ki. The combination recited in claim 2, wherein the sewing needle andpresser foot assembly are` mounted in a plane transverse to the plane ofthe supporting standard, so as to sew a seam substantiallyperpendicularly to the plane of said supporting standard.

5. The combination recited in claim 1, wherein the supporting standardis a flat plate of uniform'thickness; the housing is made up ofsubstantially similarly shaped and recessed shells which meet in mutualopposition along a longitudinal plane disposed substantially centrallyof the housing, said plate being disposed in a plane substantiallyparallel to but orset laterally from the said longitudinal meeting planeof the shells; and mutually spaced, removable and replaceable fasteningdevices securing saidl shells together and to said plate.

6. The combination recited in claim 5, wherein an electric motor issecured to a lower part of said plate and rests upon the said base atthe side of said housing within which said plate is offset, said motorbeing enclosed by a shell which joins the Ysaid housing; and meanssecuring the housingV and said motor shell to the said base.

7. The combination recited in claim 1, wherein the supporting standardis secured to the base, andthe housing is removably and replaceablysecured to said standard.
